CVE-2023-38037

Summary

CVE-2023-38037 is a vulnerability affecting ActiveSupport::EncryptedFile in Ruby on Rails. The issue arises from the temporary files created during encryption having default file permissions, which conform to the user's umask settings. This means other users on the same system might gain read access to these files, potentially exposing sensitive data being edited by a user. Attackers could exploit this vulnerability by reading the contents of temporary files while they are being processed. All users running an affected release should upgrade or implement workarounds to mitigate this risk.
